AbstractIn cases of life-threatening status asthmaticus which are refractory to drug therapy, the administration of inhalation anesthetics can be life-saving as they help alleviate bronchial spasm. We had an 11-year-old female patient suffering from status asthmaticus who was moribund from severe CO2 narcosis and was not responding to any of the conventional therapies. She finally fell into ventricular fibrillation. After cardiopulmonary resuscitation, we administered 2.0% isoflurane in oxygen. Within half an hour, her high inspiratory pressure was dramatically decreased, and then the isoflurane concentration was maintained at 1.0%. After 14 hours of isoflurane anesthesia, PaCO2 decreased to the normal level and the isoflurane treatment was discontinued. The endotracheal tube was removed 4 hours later. She had an uneventful recovery and was discharged from the hospital 11 days later. With its low metabolic rate and therefore low organ toxicity, as well as its low arrhythmogenicity with remarkable bronchodilating activity, we feel isoflurane may well be superior to other inhalation anesthetics in the treatment of status asthmaticus.
